Robert Griffin III endured a rough night as the San Francisco 49ers (7-4) left the American capital with a 27-6 win on a bitterly cold Monday night.
The Redskins (3-8) quarterback was put on his back four times - once in particularly brutal fashion - as his side slipped to 3-8 on the season.
For Kaepernick, another under-fire quarterback, it was one of his best games of the season. The 49ers QB threw for three touchdowns and 235 yards for a career best 134.5 passer rating.
The Redskins clearly came in with a game plan to stop 49ers running back Frank Gore, and they successfully limited the powerful back to just 31 yards on 13 carries.
They dared Kaepernick - who hadn't thrown for more than 200 yards in his previous four games - to throw downfield, and he did just that.
He completed 14 of his 24 passes, including two touchdown throws to Anquan Boldin and one to tight end Vernon Davis.
"Colin, he's been taking a lot of criticism, but one thing I like about Colin, he's always hanging in there," Davis told ESPN after the game. "He's always fighting through adversity.
"He's one of those guys who's tough."
Having lost to the Carolina Panthers and the New Orleans Saints by a combined four points, the 49ers were under pressure to get back to winning ways in the marquee Monday night match-up.
They were up against one of the stand-out quarterbacks from last year's famed rookie crop, but unlike class of 2012 peers Russell Wilson and Andrew Luck, Griffin III has suffered a disappointing 2013.
Under pressure from the 49ers' fierce front seven all night, the former-Baylor gunslinger passed for just 127 yards, an interception and no touchdowns.
"We've got to conquer some of the demons that we have going on as an offense and just as a team in general - and I think we will," said Griffin.
"It takes all of us."
Griffin was slammed by the media last week for failing to take responsibility for two straight losses to the Minnesota Vikings and Philadelphia Eagles, with even teammate Santana Moss publicly questioning his leadership skills.
This defeat will do little to lift his confidence, and the Redskins now sit bottom of the NFC East having won the division last year.
Next up for Mike Shanahan's team is a home game against divisional rivals New York Giants next Sunday evening.
